The orchestration of incivility happens, too, and it is evil. Liberal power of all sorts induces an organic and crazy-making panic in a considerable number of Americans, while people with no particular susceptibility to existential terror -- powerful elites -- find reason to stoke and exploit that fear. And even the most ideologically fair-minded national media will always be agents of cosmopolitanism: something provincials fear as an outside elite intent on forcing different values down their throats.

That provides an opening for vultures such as Richard Nixon, who, the Watergate investigation discovered, had his aides make sure that seed blossomed for his own purposes. "To the Editor . . . Who in the hell elected these people to stand up and read off their insults to the President of the United States?" read one proposed "grass-roots" letter manufactured by the White House. "When will you people realize that he was elected President and he is entitled to the respect of that office no matter what you people think of him?" went another.

Liberals are right to be vigilant about manufactured outrage, and particularly about how the mainstream media can too easily become that outrage's entry into the political debate. For the tactic represented by those fake Nixon letters was a long-term success. Conservatives have become adept at playing the media for suckers, getting inside the heads of editors and reporters, haunting them with the thought that maybe they are out-of-touch cosmopolitans and that their duty as tribunes of the people's voices means they should treat Obama's creation of "death panels" as just another justiciable political claim. If 1963 were 2009, the woman who assaulted Adlai Stevenson would be getting time on cable news to explain herself. That, not the paranoia itself, makes our present moment uniquely disturbing.

It used to be different. You never heard the late Walter Cronkite taking time on the evening news to "debunk" claims that a proposed mental health clinic in Alaska is actually a dumping ground for right-wing critics of the president's program, or giving the people who made those claims time to explain themselves on the air. The media didn't adjudicate the ever-present underbrush of American paranoia as a set of "conservative claims" to weigh, horse-race-style, against liberal claims. Back then, a more confident media unequivocally labeled the civic outrage represented by such discourse as "extremist" -- out of bounds.

The tree of crazy is an ever-present aspect of America's flora. Only now, it's being watered by misguided he-said-she-said reporting and taking over the forest. Latest word is that the enlightened and mild provision in the draft legislation to help elderly people who want living wills -- the one hysterics turned into the "death panel" canard -- is losing favor, according to the Wall Street Journal, because of "complaints over the provision."

Good thing our leaders weren't so cowardly in 1964, or we would never have passed a civil rights bill -- because of complaints over the provisions in it that would enslave whites.
